One of my very favorite western movies - - except that according to this article his name in the move was Dunson.  That's incorrect, sorry!  His name in the move was DUNSTON.

Watch the movie and see if I'm right.

Montgomery Clift was also in this movie (as John Wayne's character's "adopted" son.  I CAN'T STAND THAT GUY, NEVER COULD.  Didn't matter what kind of movie he was in, western or otherwise, I just didn't like the guy.  Go figure!
